jquery callback methods for asynchronous loop to finish

By -
Some times jquery loop statement will not wait until the ajax call completion.
For this case we can use the jquery callback method for looping ajax calls.

In the below example arrayValue is passed into a call back function. this function will  be executed until we call the 'callback()' (which is called in the else part).
we need to write this function inside a function.

function parentFunction()
{
var deferred = $.Deferred();


 (function Task(i,callback)
{
if(i<arrayValue.length)
{ 
/*your code here*/
var temp = yourFunctionCall(arrayValue[i]); 
temp.done(function()
{
Task(i+1,callback)
})
}
else
{
//this call will terminate the function
callback();
}
})
(0,function(){alert('Completed');deferred.resolve();});


 return deferred.promise(); 
}
